India's state-owned Oil and Natural Gas Corp said
ONGC's first debt issue in more than a decade would likely buy the government's 51.1-per cent stake in refining and marketing company Hindustan Petroleum Corp Ltd
New Delhi, which has about a dozen state-owned oil and gas companies with significant overlaps in operations - is trying to create a large integrated energy firm.
ONGC, already the country's biggest explorer, would become India's first group with operations spread across exploration, production, refining, and marketing of petroleum and its products after the acquisition.
ONGC said it would seek shareholder approval for the debt issue at its annual general meeting on Sept. 27.
It had not decided on the mechanism, saying it could be issued in Indian rupees or foreign currency through bonds or non-convertible debentures in domestic or overseas markets.
ONGC is on a major capital expenditure programme and plans to spend close to $5 billion over the next few years to develop its natural gas fields in the east coast.
